I was observing the planets (5 of them visible this evening). While trying to orient myself I saw a four or five faint lights in a tight formation pass directly overhead in a NNW direction. I thought that it might be a plane, a single object but I had a sense that they were separate because the lights were of different intesities. Because of the faintness of the lights they seemed high yet if they were high then they were going FAST! There was no Sonic boom or anything. It was weird! The objects cleared a 90 degree arc in less than three seconds.
